AC BIO 430

Auguste Cryogenics developed the stainless steel containers in this series from the ground up using state-of-the-art technology. They are specially designed for the safe and economical long-term storage of larger sample quantities and are therefore used in the fields of medicine, pharmaceuticals and research.

The vacuum-insulated products come with Auguste Cryogenics' GOLD-standard vacuum and offer a remarkably high storage capacity in a clear, smooth-running aluminum storage system on one level for the AC BIO series and two levels for the AC IVF series.  The containers of both series are characterized by very low nitrogen consumption at a stable storage temperature, which almost reaches the cold level of liquid nitrogen even in the gas phase.

The lid of the container opens easily and wide, allowing easy access to the contents. It is convenient to clean and is equipped with a control switch that, in addition to an "open lid" detection, can also send other control signals, for example for automatic demisting or rapid cooling.

Auguste Cryogenics Medical Family Freezer Series vessels can be supplied with automatic filling and control systems to ensure a regulated supply of cryogenic liquid nitrogen and continuous monitoring.

MDR – Medical Device Regulation (EU)
The Medical Device Regulation (MDR) defines harmonized requirements across Europe for products intended for medical applications. MDR-compliant nitrogen containers meet the highest standards in terms of safety, quality, and documentation, and are specifically designed for use in sensitive environments such as medical, laboratory, and research settings.
They offer verified reliability, compliant design, and full traceability throughout the entire product lifecycle.

Function:

The cooling effect required for cryogenic sample storage is generated by the continuous evaporation of the liquid nitrogen refrigerant. The necessary heat of vaporization is extracted from the environment by heat transfer. As a result, the liquid nitrogen level in the deep-freeze storage tanks is constantly falling.

Regular, controlled refilling is therefore required (automatically or manually). This results in the liquid level curve shown here. In order to prevent unnecessary nitrogen losses and icing of the storage containers, liquid nitrogen should be refilled at pressures between 0.7 bar - 1.4 bar only.

The insulating properties of the Auguste Cryogenics Medical Family are essentially based on the presence of a vacuum between the inner and outer container. A vacuum loss inevitably leads to a very high increase in nitrogen consumption and poses a risk for the stored samples if there is no refill with liquid nitrogen.
